When trying to make write an apostrophe like Brian's or something like that posting/updating an existing post changes this into Brians

What's more is every time the post is updated the number of " increases by 1 so updating a post that WP converted Brian's to Brian''s would then become Brian'''s and so on this is increasingly annoying and I see no way to fix this. I was told this was most likely a bug and I should report it here so here I am.

I usually update via a client so this goes un-noticed for some time until i get emails asking why i have 12 apostrophes. I have made posts from the back end of WP 3.0 to test this as well and it exists so the bug i am guessing is on the code level not the client level.

I added this under the editor component not sure if this is right please feel free to move it and take it easy this is my first bug report to WP

It seems Trac will not let me type out to many (') for demonstrating the error so i added two screenshots one to represent the back end and one the front end showing the error exists on both sides. If you need a link to see the blog itself let me know do not want to promote my blog here so will not post the link unless asked.
